Gladwell on overconfidence

This week's New Yorker carries a Malcolm Gladwell piece about overconfidence - how it contributed to the collapse of Wall Street and everything else. So, the bankers were overconfident? No kidding. In another writer's hands, this might have been an investigation into ursine defecation patterns, but MG handles his topic with typical elegance. I liked this:

Of course, one reason that over-confidence is so difficult to eradicate from expert fields like finance is that, at least some of the time, it’s useful to be overconfident—or, more precisely, sometimes the only way to get out of the problems caused by overconfidence is to be even more overconfident.
From an individual perspective, it is hard to distinguish between the times when excessive optimism is good and the times when it isn’t. All that we can say unequivocally is that overconfidence is, as Wrangham puts it, “globally maladaptive.” When one opponent bluffs, he can score an easy victory. But when everyone bluffs, Wrangham writes, rivals end up “escalating conflicts that only one can win and suffering higher costs than they should if assessment were accurate.” The British didn’t just think the Turks would lose in Gallipoli; they thought that Belgium would prove to be an obstacle to Germany’s advance, and that the Russians would crush the Germans in the east. The French, for their part, planned to be at the Rhine within six weeks of the start of the war, while the Germans predicted that by that point they would be on the outskirts of Paris. Every side in the First World War was bluffing, with the resolve and skill that only the deluded are capable of, and the results, of course, were catastrophic.


Still, not classic Gladwell, and certainly not the wonderful underdog story from earlier in the year.
